DOOR-FRAME.

To all whom 2'15 may concern:

Be it known that we, (VALTER EMILE CHAnRoN and Louis NAroLiioN RICHARD,both subjects of the King of Great Britain, and residents of the city ofOttawa, Province of Ontario, Dominion of Canada, have invented certainnew and useful Improvements in Door-Frames, of which the following is aspecification.

Our invention relates to improvements in tent doors and the like and theobject of the invention is to devise a simple, effective and cheap tentdoor and frame, both of which can be readily taken apart for packing.

A further object is to construct a tent door and. frame to which thecanvas of the tent can be readily applied to and easily detachedtherefrom.

Our invention consists of a door frame comprising uprights, a cross barextending across the top of the uprights, said cross bar being ofgreater length than the lateral dis tance between two uprights, boltsextending through the cross bar and down into orifices in the top ofeach upright, a lower cross bar near the bottom of the uprights, boltsextending through the uprights into orifices in the ends of the lowercross bar, hooks secured to the lower cross bar designed to engage pinson the uprights, braces straddling the ends of the upper cross bar andhaving divided lower ends designed to spring into apertures in theuprights of the frame, a door comprising uprights, cross bars extendingacross the bottom and top of the uprights, bolts adjacent to the ends ofthe cross bars extending through the same and down into the orifices inthe ends of the uprights of the door, hooks secured to the in side facesof the uprights and designed to be inserted into eyes adjacent to theends of the cross bars of the door in order to hold the uprightssecurely against the cross bars, braces of inverted U -shape ext-endingthough the upper cross bar on each side of the center thereof, the lowerends being designed to spring into apertures in the upright of the door,canvas having the edge thereof turned over around a rope, plates havinga curved edge designed to be secured to the door and to the frame, thecurved edge being so constructed as to bear against the beaded or ropededge of the canvas, and thus when the plates are secured to the doorSpecification of Letters Patent.

and frame the canvas will also be held there to, all as hereinafter morefully set forth and described in the accompanying specification anddrawings.

In the drawings: Figure 1 represents a front elevation of the door andframe. Fig. 2 represents a perspective detail of a corner of the door.Fig. 3 is a detail of one of the inverted U-shaped braces. Fig. 4c is asimilar detail of one of the lower corners of the door. Fig. 5 is aperspective detail showing the brace applied to the upper cross bar ofthe frame. Fig. 6 is a sectional elevational detail showing the methodof inserting the bolts into the members. Fig. 7 is a cross section ofthe edge of the canvas showing the method of inserting the rope into theedge thereof. Fig. 8 is a cross section broken away intermediately ofthe door and frame showing the plates for securing the edges of thecanvas to the door and frame respec tively.

In the drawings like characters of reference indicate correspondingparts in all the figures.

1 are the uprights of the frame. 2 is the upper cross bar thereof.

3 is the lower cross bar.

4 are the bolts extending through the upper cross bar and down intoapertures in the ends of the uprights 1.

5 are bolts extending horizontally through the uprights and intoorifices in the lower cross bar.

6 are hooks pivotally secured to the lower cross bar and designed toengage pins 7 on the uprights.

8 are braces of inverted U-shape straddling the ends of the upper crossbar, the lower ends being inserted into apertures in the upper ends.

9 are the uprights of the door. 10 and 11 are the upper and lower crossbars thereof respectively.

12 are braces of inverted U-shaped form extending through the cross bar10 and the lower ends designed to be sprung into apertures in theuprights 9 of the door.

13 are pins extending through the cross bars and into orifices in theuprights of the door.

14 are hooks pivotally secured to the up rights of the door and designedto be inserted into eyes 15 secured to the cross bars g engaging dooriand frame and the hooks 6.1

the same securely in place when the nuts of the bolts 21 are screwed up.23 are hinges secured to one upright of the frame and.

door.

It will be seen that iuorder to take down the frame and door all that isnecessary is to pull the ends of the braces 13 and 12 out of theapertures in the uprights ofthe dis- Similarly, by disengaging the hooks14: the doorwill come apart.

' The canvas is taken off by partially unscrewing the bolts 21 andloosening the plates when the beaded edges ofthe can vas will be free tocome away from the door and frame. In assembling the door the oppositetakes place.

Of course it will be understood that our device can with equal facilitybe appliedto windows as well as doors and window net} or ting, sheetcelluloid, talc or the like may be used for this purpose instead of thecanvas and also netting of the different kinds may be used for the doorif desired, instead of canvas.

In small conical shaped tents we may find it desirable to continue theuprights of the frame above the upper cross bars which will be situatedbetween the two uprights and afiix the braceto. the projections of theuprights and to the upper cross bar thus saving a certain amount ofwidth.
